Although the tutorial is not very long, you may find that you want to exit the project before you have finished. If you save and name it now, you will be ready to exit whenever is convenient. To save the project:
Click the Save Project button (third from the left at the top of the Protege window). You can also choose Save Project from the File menu. The Protege Files dialog box will open.
To choose the location where you want the project to be saved, click the top button at the right of the Project line. In the Project Files dialog, navigate to (and/or create) a directory.
Enter a File Name (e.g., "tutorial").
Click on Select to proceed.
You will be returned to the Protege Files dialog box. Click OK to save the files and exit the dialog.
Note: You can also choose a location by typing the full path name in the Project line. The names of the other files will be filled in automatically.
